Volume of a hemisphere is 2/3•pi•r^3
The answer is 56.5m^3
-23 - -39
equals -23+39 because 2 minus signs = a plus sign
-23+39=16
the answer is 16
19.899 as an approximation
2 sqrt (99) = 6sqrt (11) exactly
A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16
